When Albus Potter proved unable to get his broomstick to rise off the ground during their first flying lesson with Madam Hooch, Polly disparaged him, stating that he wasn't "like his father at all."[2]

Second year

During a Potions lesson in their second year, Polly once again teased Albus, calling him an "irrelevance" and suggesting that even the school's portraits tried to avoid him when he walked past.[2]

Fourth year

Polly's life was briefly changed in 2020 when Albus and Scorpius altered the past. In an alternate reality, Albus was in Gryffindor as well. However, in their Defence Against the Dark Arts lesson taught by Hermione Granger, Albus questioned Hermione about the changed circumstances which prompted her to deduct points from Gryffindor.[3] Polly angrily accused Albus of losing points on purpose because he "hate[d] Gryffindor and everyone [knew] it."[3] Professor Granger told Polly to sit down before she was forced to dock even more points.[3] Later, when Albus and Scorpius were discussing how their actions had changed history in the Hogwarts library, Polly shushed them.[4]

Her life was changed again when Albus and Scorpius meddled with the past a second time. Polly still attended Hogwarts in a world where Voldemort won and Albus was never born. Polly asked Scorpius whether he intended to invite her to the Blood Ball.[5]

Personality and trait

Polly Chapman was a very confident witch. She tended to speak her mind and was unafraid of asking for something she wants - such as asking Scorpius to the Blood Ball in an alternate universe. Her wit was as sharp as her tongue, but could sometimes be harsh, especially toward shy and unsure Albus Potter.
